Question

Triangle D E F is a dilation of triangle ABC with scale factor 2. In triangle ABC, the largest angle measures 82. What is the largest angle measure in triangle DEF?

Answer 1

Answer: 82°

Explanation:

• Dilation is a transformation that creates an image that has the same shape as the given figure, but has a different size.

• After dilation , angles remains the same but measure of sides changes.

Given: Triangle DEF is a dilation of triangle ABC with scale factor 2.

In triangle ABC, the largest angle measures 82°, then the largest angle measure in triangle DEF should be 82°.

So, the largest angle measure in triangle DEF = 82°
